In this assignment, you will use integration to compute the volumes of solids whose cross-sections are given by a specific shape. For each of the solids described below, set up and evaluate an integral representing the volume of the solid. Show all your work. You will not receive credit for answers that do not contain supporting work. When you are finished, scan or take pictures of your written work and upload it for grading. 1. The base is the region bounded byy = Vaz + 9, y - O. - O and a - 4. All of the cross sections cut perpendicular to the x-axis are squares. 2. The base is the region bounded by y - Vaz + 9,x - O and y - 5. All of the cross sections cut perpendicular to the y-axis are squares. 3. The base is the region bounded by y = va2 + 9. y - O.a - Oand : - 4. All of the cross sections cut perpendicular to the x-axis are rectangles with height equal to x. 4. The base is the region bounded by y = Va2 + 9. y - 0.x - Oand x - 4. All of the cross sections cut perpendicular to the x-axis are semicircles
